I don't see any need to extend the legal use of next/prior to anything
else than iterators. I considered the fact that it works/worked for
non-iterators an accident as the documentation only speaks about
iterators and never bothers to mention non-iterators. Thus, the bug is
IMHO that it's not explicitly documented that next/prior's first
argument must meet the interator requirements.
